Web16 apr. 2015 · With tertiary alcohols, H2O can then leave, resulting in a carbocation. If a strong acid such as H2SO4or p-TsOH is used, the most likely result is elimination, since the conjugate bases of these acids (HSO4–and TsO–) are poor nucleophiles and unlikely to add to the carbocation. Table of Contents Web16 apr. 2015 · The identity of the acid is important. In the case of H2SO4 or H3PO4, there simply is no sufficiently strong base present to cause an E2 reaction to occur.

Who are the experts? Experts are tested by Chegg as specialists in their subject area. WebH2SO4 and CH3OH are reacted to form methoxymethane and water respectively. The reaction occurs in two steps: At first, methyl hydrogen sulphate is formed. CH3OH + H2SO4 → CH3O-SO3H + H2O. Adding more acid, we get the dimethyl ether. CH3OH + CH3O-SO3H → CH3-O-CH3 + H2SO4. This process is known as etherification. WebCette réaction, appelée aussi estérification de Fischer ou estérification de Fischer-Speier, consiste en la production d'un ester et d' eau, à partir d'un alcool et d'un acide carboxylique. L'équation générale de cette réaction est : Cette réaction conduit à un équilibre chimique. ship seaworthiness
